ET24 high frequency filter bobbin ，This product is made of PBT material, which can withstand high temperatures of 120-150℃. It is suitable for high-temperature environments such as car engine compartments and industrial frequency converters, ensuring stable filtering performance. The dielectric strength is ≥20kV/mm, and its high insulation eliminates the risk of high-voltage short circuits, making it suitable for safety-sensitive fields such as new energy and medical care. Impact resistance up to 20kJ/m², vibration resistance, protection of winding structure, and extended service life. Resistant to oil, moisture and solvents, it can withstand complex environments without additional protection, reducing maintenance costs. The dimensional tolerance is ≤0.1mm, ensuring precise fit between the winding and the magnetic core, and consistent filtering effect. Compliant with UL94 V-0 flame retardant standards, it enhances equipment safety and facilitates compliance certification. To ensure the stability, safety and durability of equipment in industrial, automotive and other fields.
